Be 1t known that I, citizen of thc United States, residing at Boston, in the county of Suffolk and State of Massachusetts. have invented certain new and Juseful Improvements in Electric Signaling Devices for Elevators, of which the following is a full, clear, and exact specification.

My invention relates to electric signaling devices for elevators, and my general object is to improve upon the constructions heretofore used, and particularly to improve upon the construction set forth in my prior pat- One of several objects of my present invention is to provide a signaling system which is adapted for use With two or more elevators, whereby all cars going in the same direction may be signaled from a single push-button in conjunction with means for controlling the signals of the cars by means of suitable devices to be operated by the car operator, such, for example, as the floor gates or doors which are arranged alonglr each elevator shaft at each floor.

Other objects of the invention Will become more clearly apparent from a thorough understanding of the invention.

Another object of my invention is to pro` vide an improved construction by Which the device or mechanism which causes a signal or signals to be given or operable may be maintained in such signal-giving position and restored to normal condition.

ln the drawings which show the preferred form of my invention, Figure 1 represents a side elevation: Fig. Q an end elevation of the overhead mechanism for controlling the circuits; F ig. 3 is a diagram of connection foropei'ating the signalsgin the cars; and Figs. 4 and 5 are detailed diagrams.

(En the overhead of each elevator is provided the construction shown in Figs. 1 and 2, which may be used if desired. The gear 1 is driven from the overhead sheave of the elevator and meshes with the gear 2, which drives the worm shaft 3 mounted in the frame 4. The carriage 5 meshes With the worin f3 and is moved to the right or left bv Specication of Letters Patent. Application led October l. 7, 1904. Serial No.

makes a connection with the Contact 9, 10, 11, and with the switches and stops 7 are provided at each end of the Worm. The operation of these parts and their connections need not be more speciiically described because it forms no part of the present invention.

The belt 13 transmits motion to a grooved barrel 16 mounted on the shaft 15, and meshing with the barrel is a gear 35 also carried on a Worm shaft 33 so that it moves to the left or iight, depending on the direction of movement of the car. 34, 34 are suitable stops at the end-of the same. The train of gears 36, 37, 18 transmits motion to a shifting switch which, in the present instance, is illustrated for two floors only and comprises tivo levers 19 and 25 and suitable contact plates hereafter to be more specically described.

31, 30, 29 is a suitable friction connection so that the switch will be thrown to the left Vfrom its position shown, until it abuts against a stop 39 when the car reverses its direction of movement. Such friction actuated shifting switches are so common in this art that it is not considered necessary to more specifically describe the same, as no claim is herein made to the specific form of mechanism for accomplishing such shiftplates 107, 108,

1n Tn the diagram of Fig. 3, A represents one car and B represents another car, which are supposed to be traveling in their respective shafts or Wells and which pass the gates 40, 4-l`and 42, 43. The gates open in the direction of the arrows. Each of the cars is lprovided with electrically-operated signaling mechanisms for signaling the operator to stop at the floors, and such signaling mechanism is preferably an electric lamp, one for each floor in each car. The lamp 44 in car A and 45 in car B being signals to stop at the fourth floor, and lamps 46 and 47 at the third floor. In the present instance only one lamp is used for each Hoor as this is the preferable construction.

4S. 49 represent devices to hepperated by the intending passenger on the ourth lioor when he desires to signal the car, and Which l have genericall \v termed passengcrs i buttons, and fil). 5l are similar buttons for the third Hoor. The means for operating a Patented Aug. 25, 1914.

signal comprises one of these passengershuttons and mechanism correspondingr to, and set hy, each button, such, for example, as a normally-open switch which is closed to close the circuit through the signal lamp, preferably as soon as a push-hutten is operati-d. r[he specific mechanism above re- Yl'errrd to as corresponding to, and set by, rich huttou, preferably comprises a switc i, such as indicated at 52 or 53, which may be clomid hf.' a reciprocating core 54 or 55 of a seizing magnet. The normal circuit is indicati-d. lor example, in Fig. 5. The circuit throagh lamp -l-l is norm-.illy open at 52, and from the point 5u a branch circuit goes through the down setting magnet 57, through the uninsulated portion ot the core D# of the down restoring magnet 59, and by wire UO to the normally-open passengers: laittou i9'. and from there to the stationary cout-ict plate 22, and Ly vswitch arm 19 to the contact plate 20, and so to the other side ot' the source ot electro-motive-force. This will energize the setting magnet 5T, which u ill cause its core 5l to more up and close the circuit through the lamp i4. G1 is a conducting piece carried by the core 54 but insulated therefrom by insulating material of. As the push-hutten 49 is usually springprcsscd so as to open as soon as the intending imssenger takes his finger oil, it is desirable to provide a` maintaining circuit which will keep the magnet 5T energized and the switch 52 closed. Then the button is pushed the core moves from a normal position shown in Fig. to the position ot the saule core il shown in Fig. 3, and a branch circuit fiom the magnet 57 is thus closed hy way of wire Si, conducting piece 61, wires o3 and GG, which keep the magnet energized even though theV passenger takes his linger oli' the push-button i9, and thus maintains the magnet circuit closed and the signal lamp lighted and gives a signal to the operator to stop at the lloor to which that .lamp corresponds. lVhen the operator stops at a floor, he operates a switch to break the circuit of the setting magnet, which allows the core to drop and restore the circuits to their normal condition. I have shown at G7 such a normally-open switch in Fig. 5 which, when closed,` closes a circuit 'which may be traced from said switch to the arm 19, stationary Contact GS, through the down restoring magnet 59 and out' by wire GG. This energizes the magnet, raises the core 5S until its insulated portion 69 hreaks the circuit through the magnet 57, thus allowing the core of the setting magnet to drop aiid open the lamp circuit, and when the gate is again shut the switch G7 automatically opens the restoring magnet circuit and thus the parts are all restored to their normal condition. The down setting magnet G9 and down restoring magnet have corresponding circuits so as to he controlled from the down hutten 5l to control the light (5, and the switch arm for the third floor makes contact with a stationary plate 71 corresponding to the plate (3S. The door switch 79 of gate -ll also controls the restoration 1u the same manner. ln other words, when the car is moring down the shifting switch stands in the position shown at the upper left-hand portion of Fig. 3, and for each floor there is provided a stationary restoring Contact G8 or 7l and a corresponding arm li) or 25 in electrical contact therewith;` and a common vcontact 20. Vhen the car reverses its direction ot' n'ioi'ement the switch arms 19 and 25 are thrown forward to the opposite position, that is. to the position illustrated at the upper right-hand corner ol Fig. f3, in which the arms i9 and l5 will contact with the stationary plates T3 and 74. and the upper end ot' the arm 19 with the plate 23, so that the up hutten will control the lights ol:I that car which is moving up and the operation ot the corresponding gates will restore the circuits in a similar manner. lleterring to car B at the right. which is assumed to he going up and in which the up`7 push-button 50 ot the third tloor has heen operated so that a circuit has been closed through the up "-setting magnet T3, core TG oi the "up"-1'estoring magnet 7T, the conducting portion TS otniagnet T5 and out as shown by the arrows to the source of electro-motive-force T9, this has closed the switch SO and the circuit through the lamp -lT of car li, which corresponds to the third loor. llvlien, now. the rar reaches the third ioor and the gate lil is opened, a circuit will he closed from the source of electroniotire-force T9 through the wire 81, through switch 82, arui 83 and stationary plate Si ot the circuit shifting switch, through the up ""restoring magnet TT, and out to the other side ot the source of electroniotive-i'orcc. rl`his will raise the core To and hreak the circuit through the setting magnet T5 in the same way. It the up push-hutten. i8 is pushed, it will oliviously close the circuit through the up setting magnet S5 and light the lamp in the car,` and the parts will he restored to their normal condition when the gate l2 is opened, as this will energize the "up restoring magnet 86 in the same manner.

Down setting magnets S7 and 8S and re-string magnets 89, 90 for ear B with corre-1 sponding stationary Contact plates 91, 91%, and contact plates 9i, 95 and 96 corresponding to the similar plates 20, E2 and Q23, are provided and the up-setting magnets 9T, 9S and restoring magnets 9,9, are provided for controlling the signals when the car A. is going up.

As shown in Fig. '-l, the restoring magnets are in parallel so that if, for example, both cars are moving up and both lights for the fourth l'loor have been lighted, the opening of either gate 42 or 40 will energize both the up-restoring magnets for that floor and so restore both the corresponding signals to their normal condition.

l t will be observed that each of the shifting switches normally limits the restoration to that one or those push-button set mechanisms which correspond to the direction in which that particular car is moving, that is, if the car A, for example, is moving down, its circuit-shitting switch so controls its door switches that the opening of the gate 40 or 4l can only cause the energization of the down restoring magnets and will not atleet the up restoring magnets, and vice versa it the car is moving up. In the embodiment shown each door switch is connected to a separate arm of the circuit` shifting switch and for each such arm an up and a down restorin contact is provided (such as 74 and 7l or the door switch 72) and each one of these contacts is connected through the corresponding -magnets of that fioo'r in parallel and to the corresponding stationary contact of the shifting switch of the other elevator, as shown in Fig. 4;.

It will also be observed that inthe embodiment shown in the drawings there is only one wire running from each door switch and only one switch, that is a single wire at the gate, and this single wire and switch controls thefrestoration of the up setting magnets for that floor, as well as for the down setting magnets for that floor. This is preferably accomplished by providing a single switch having a single break or open point. This is a distinct improvement over, for example, the McLean Patents 748,408 and 748,409 as the Wiring and switch construction is cut in half to accomplish the same results. The shifting switches which also control the restoring circuits are operated by the cars because they are thrown from their up to their down position, and vice versa by the cars as they reverse their direction of movement wherever the cars may be in their shafts. The gate switches are, in the embodiment shown in the drawings, normally open, and this is the preferable construction.

The passengers-button-set device, which causes a signal to be given in the sense that the signals controlled by it cannot be given except when such device has been set, is shown in this embodiment of the invention as a movable, weighted device such as indicated in Figs. 3 and 5, which is moved into its signal-giving position when the floor hutton is operated. It is preferably moved into position by a magnet, and `is so shown. When released the device automatically moves back to its normal position, thils restoring the signal to normal condition. lVhen it moves to its signal-giving condition, it calls into operation means which are adapted to hold it in such position that it may maintain the signal after the floor-button has been operated, and this is preferably accomplished by theautomatic closure of a maintaining circuit through a magnet. In the specific construction illustrated, when the core 54 moves up to its signal-giving position, it calls into operation the maintaining circuit through the magnet 57, which holds the core,`by the normally-open switch at 01. I consider it preferable to make the'setting magnet also serve as a holding magnet, but do not limit myself to this construction.

If the passengersbuttonset device is held in its signal-giving position by a magnet as in the specific construction illustrated, I provide suitable means to denergize said magnet and release the same so that it will autoi mat-ically move back to its normal position, preferably by its own weight. Such deenergization is preferably accomplished or controlled by a normally-closed switch in the maintaining circuit which is opened at the proper time. In the embodiment illustrated in the drawings, such a switch is indicated at 58, 69 in Fig. 5, which is automatically opened when the corresponding floor gate or door switch 67 is operated. In the Smalley and Reiners 634,220 and the Collett 034,229 patents the restoring magnets are controlled by stationary contact plates -corresponding to. the floors and a moving brush which passes over them, such Contact plates .and brush being termed a commutation I prefer to energize the restoring magnets in succession by a form of commutator or circuit-selecting device in which the switch mechanism, instead of being stationary contacts which correspond to the floors as in the said patents, shall have mechanism corresponding to each licor which are operated b the door gates. It will be obvious that t ere is corresponding to each floor a restoring magnet such as 59, and suitable switch mechanism for operating the same such as a door switch 67, and that, as such door switches may be closed in succession, they may accomplish the same general result as the form of commutator illustrated in Said prior patents, as both of said atents, as well as my device, comprise switci mechanism corresponding to each floor for controlling the restoring magnets.

In order that the down restoring magnets, for example, may not be energized eX- cept when a car is going down, the rocking arm 19 which is operated automatically by the car, is provided. This serves to render the up restoring magnets operable only when a car is moving up, and the down closing the circuit through restoring magnets o erable only when a car is moving down. n the speciiic embodiment illustrated in the drawings it serves to connect the single door switch of any car with the up or the down restoring magnets corresponding to that floor.

I am aware that variations from the construction shown may be made without departing from the spirit of my invention as claimed, and I therefore do not desire to be limited to the particular construction shown in the drawings.

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent, is,
